Wasn't bad luck. I blame myself really.

My 2010 had index 6 injectors, a driveway tuneup (new plugs and coils, oil change, coolant flush) and 80k+ miles.

Everyone reviewing feels the injectors (and associated boost) played a part in the two bent rods.

Quite a costly mistake.

As mentioned above, DME tuning would be my recommendation. Joining forces between the JB4 and a DME tune would be the preference. I'll run the JB4 again on this build, but only to keep my kittyless light from coming on. That is, until I can get a DME tune and see the live outputs of it's tuning before adding e30/JB4 use.

I feel a swap to TU mannies and turbos combined with blankets and DP wrap with the DME tune is the winning combo here. Our community just needs to get a committed tuner stateside to deliver with consistency. As it stands now we are the bastard platform.

In all honesty, if we can accomplish the above I feel we can control our resale value to some degree. This platform is KBB'd to $20k-$25k right now. If we can solve the S63 to S63TU power disparity with some consistency the difference between E and F platforms is minimized.

TL;DR - E70/71 with a reliably configured AVIN unit in the dash and similar F-body (ouch on the terminology) power numbers at a $20k-$30k discount would be a steal.
So per your suggestion, install DP, have it DME tuned, then use JB4 for controlling Meth injection? Then perhaps further DME tuning?
